hello yellow, being used to a pc rather than a mac, been searching for defrag prog, found norton defrag but not managed to install it properly, just wanted to know if there was any way i could do it as prog's running slow, A

Yeah, I'd assume it's something else too. In my experience slow performance was due to an errant process going haywire. Any particular application giving you problems? In the Applications/Utilities folder there's the Activity Monitor. You can view the running processes to see if any particular application is causing the problem.

I don't know what version you are running, but the classic (OS 9.2) and MAYBE 10.0 - not sure - uses a "rebuild desktop". When you start up, before all your desktop "fluff" begins to appear, hold down your control-option-apple keys all at the same time. Keep holding them until the computer asks if you are sure you want to rebuild your desktop. Select "yes". It is very similar to defraging, and the longer it's been since you last rebuilt, the longer it will take - but usually only a couple minutes.
